. xmnovnn LUBRICATQR.

\ be Schedule referred tain thon Letten PatentA and making part of thesame.

Be it' known tlrat"I, GREGORY Gannon, ofthe city of Albany, in thecountyof Albany and State of New York, 'ha`vc invented a. new and usefulImprovement in Lubricators; and I do hereby`declare the following tolie` a full,'clear', aud exact description thereof, which will enablethose `skilled in t-he art to make and use the same, reference being hadto the accom-4 1 panying drawingr forming -part of `tlrs specification,

` and runs downto `the journal.

` If the lubricating cup is attached to the hub of a loosc-pulley,so`that it is carried round by the same, provision must be made to retainthe lubricating malterial down at-the bottom of the cup, and toeti'ecttlrisjpurpose, a follower is litted into the cup, which bearsupon the lubricating material, being pressed i down by a spring, aportion .of which is inclosed in a tube extending from the, top of thecup, said tube being made of such a length that rooin is obtained for aspringotl `sulicientjlength to act upon the follower with the requisiteamount of power, whatever the position of said follower in the cup maybe.

4In the drawing-` -V The letter A designates a 'lubricator or oilcup,`which is provided with screw-shank a, by means of which it can bes'ec'nredjriiv `the hub of a loose pulley, or in any other articletoxwhich said luhricator is to 'l be attached.

Through this screw-shank extends'a pipe, b, which is made ofcopper, or'other good conductor of heat,

, andthe outer end ofwhich is`intendedto rest loosely u'pon the journal`of the shaft which is to be lubricated, `while its innerend bears aperforated' concave disk, c, on which the lubricating material ispacked, so that it serves to keep the 'pipe b in contact with thejournal, and also to-diuse the heat communicated by the journal to thepipe, throughout that portion o l' the lubricating material which is incontact wit-lr it.

The lubricating material scompou'nded in such a nranner that it melts ata temperature of about 110, and that it will not become liquid at theordinary temperat-nrc, butif the journal begins to heat, and the heat iscommunicated through the pipe b and disk c to tire-lubricating materialin contact withv said disk,

a portion thereof is melted and the journal is lubricated.

In order to insure a correct operationof this-device, therefore, it isnecessary that the lubricating material shall be held in contact at alltimes with the disk c.

This object is attained by a-follower, d, which is fitted into thecylindrical body of the vcup A, and depressed upontlrclubrioatingmaterial by means-of a.

spiral spring, e'. This spring must necessarily be of such a length thatit is capable to keep the follower down upon the lubricating materialthroughput the entire depth of the cup A, and in order to elect thispurpose, a tubular projection, j, has heeusecured vto the top of the cupA, said tubular projection being large enough to admit the spring, asshown i-n llrc drawing.

By this arrangement the follower is kept n"`contact with the lubricatinmaterial, even if the cup A is secured in the hub oa loose pulley, andcarried round with lthe same, the spring being made strong enough tocounteract the 'centrifugal force'of the follower.

What I claim as new, and desire to secure by Letters Patent, is v I1.'An oil-cup or Iubricator, consisting of a frame A, follower-11,spring e, disk c, and pipe b, combined, substantially as and for thepurpose described.

2. The combination of follower tl, spring e,disk c, frame A, with a topcarrying a tube, f, substantially as described. i A
